Electrogram is the world's leading provider of intracardiac digitized
electrograms. Our libraries of recorded electrocardiograms are in use by
developers worldwide. 100% of manufacturers who develop and sell
implantable defibrillators have licensed one or more of our volumes. Our electrogram database is
also in use by non-profit researchers across the globe, including the US Food and Drug Administration.

Electrogram Database Defined

An electrogram is an electrical recording of the heart using signals from the
heart itself. We have recorded the electrical impulses of the heart from
electrodes placed against actual heart tissue during hundreds of
electrophysiology studies. During these electrophysiology studies,
patients have their heart catheterized with electrodes while we use specialized amplifiers to maintain constant gain and filter settings
as we record these sessions.

Due to the nature of our recordings which include entire
EP sessions, Electrogram has collected examples of very unusual arrhythmia and
events, as well as normal sinus rhythm from the same patients for comparison
purposes.

What are these used for?

Generally, our recordings are used for one of three purposes:

To develop a new implantable cardiac device (such as a defibrillator, or drug pump)

To test a new device, such as an ICD

To conduct research developing computer programs to analyze the signals of the heart

The amount of time and effort that it takes create and annotate recordings such
as these is substantial. Collection of individual patient recordings generally
involve an entire EP surgery session .Electrogram
in turn licenses each patient data at a fraction of this cost. Our laboratory equipment consists of
opto-isolated digital amplifiers, digital tape recorders and the extensive
computer facilities required for the processing. Each session lasts several hours, and only PhDs or MDs perform the
actual recording. Once a patient recording session has been concluded, it is then edited
to ensure interesting/unusual passages are included in useful form. All passages are over-read and annotated by a cardiac electrophysiologist.
Each arrhythmia is preceded by a recorded passage of normal sinus rhythm.

Individual recordings can be licensed for between $250 and $500 each, and
if an entire volume is licensed, the average cost drops below $200. If you are
in need of a testing library for a cardiac medical device, we believe you'll
find the same thing that other device manufacturers have found: it's much less expensive to use an off-the-shelf reference library than to create one from scratch.
